you might be the one to say whether any other b.g. classes got pedestals/roller bearings. for example, i've never seen a CF, SF or DWF with them, but i suppose - at least in theory - it could have happened? Â
also, i wrote wrongly that the shot of the scrap OBFs used from holdens to simsmetal at port adelaide was in a 1994 catchpoint ... that was in the july 1992 issue, with 841 doing the honours. the rake all appear to be the third variety of OBF with horizontally reinforced doors. i think i had 1994 in my head as this train ran until that time.Ã‚Â
even in 1992 the comment is made that these OBF were the only b.g 4-wheelers in service.
looking back over issues of catchpoint prior to that time there are very fewÃ‚Â mentions of 4-wheelers, a few are:
27/11/90 - 838 hauls 2 OBF/OF in a special for steamranger to strathalbyn (jan 1991 issue)
20/3/90 - 844 conveyed 70 stored OBF from the stockwell - truro section to dry creek.Ã‚Â (may 1990 issue)
20/2/90 - 944 ran from Ã‚Â on the b.g., stabling numbers of AOGA along the route and returning to dry creek with 6 OBF for storage, a shot shows them to be third series wagons. (may 1990 issue)Ã‚Â
the july 1990 issue had a photo of the train at blyth but reported the date as 22/2/90.
24/2 and 2/5/90 - 841/833 moved some of these OBF, due to local council complaints that they were an eyesore!
2/5/90 - 805 hauls 4 third series OBF as a part of a special movement including 967 and other stock for port dock.(both july 1990 issue)
24/5/89 - N467/456 work a recovery train of 2 OBFand brakevan to assist with recovery of materials following a derailment. (july 1989 issue, photo in sept 1989)
11/1/1988 - 67 OBF returned peterborough to mile end, many for scrapping. (march 1988 issue)
27/9/87 - huge rake of SGBZ shown at gladstone (nov 1987 issue)
23/9/87 - 12 OBF hauled to storage out near stockwell (nov 1987 issue)
28/7/87 - 803 hauls OBF of super with 8 AHHE on a grain run to farrell flat (two photos sept 1987 issue).
if we take that 1992 shot of the scrap train as being the last photo of a 4-wheeler in revenue service, there's a whole big five year gap before the shot at farrell flat which is next-to-last shot of an OBF in actual revenue service i can find. that is quite a gap in coverage, really. you do start to see more pictures of roller bearing third series OBF in super service, most notably in SA diesel pictorial from early 1987 and before.
prior to july 1987 - 1 DWF, 1 Y wagon condemned in 'period under review' (july 1987 issue)
prior to may 1987 - 1 DWF, 1 Y wagon condemned in 'period under review' (may 1987 issue)
jan 1987 - standard gauge grain fleet reported as 12 AHHE, 8 AHGX, 3 AHWL, some AOGL and SGCs and 62 SGBZ 4 wheel wagons! (jan 1987 issue)
so it looks like the roller bearing OBFs were largely taken out of service in 1990, and that other 4 wheelers like DWF and Ys were still being intermittently condemned as late as 1987.Ã‚Â what is surprising is that 4 wheelers dominated the standard gauge grain fleet as late as 1987.
it is a pity catchpoint ceased reporting vehicle condemnations and did not take more interest in the decline of these wagons ... you would have thought the disappearance of the style of wagon that had run on the SAR since inception over a hundred years before would have been something to note.
